Interpretation Introduction

Interpretation:

The synthesis of propanal from 1-propanol and propanoic acid $\left({\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CO}}_{\text{2}}\text{H}\right)$ is to be shown.

Concept introduction:

Swern oxidation converts primary and secondary alcohols into aldehydes and ketones, respectively. The catalyst used is DMSO (dimethyl sulfoxide), oxyl chloride in base.

Lithium aluminum hydride $\left({\text{LiAlH}}_{\text{4}}\right)$ is a strong reducing agent. It reduces carboxylic acids into aldehydes.
